' CLEANING-MACHINE.

Application filed November 12, 1915. Serial N 0. 61,054.

To all whom it may concern:

Be it known that I, VALENTINE B. CHAM- BERLAIN, a citizen of the UnitedStates, and a resident of New Britain, in the county of Hartford, Stateof Connecticut, have invented certain new and useful Improvements inCleaning-Machines, of which the following is a specification.

This invention relates particularly to a machine for cleaning metal rodsof various cross-sectional shapes, and the object of this invention isto produce a machine of the character described of novel constructionand operation. I

In the drawings Figure l is a central side .section of a machineembodying my invention.

Fig. 2 is a top view with the casing shown in section.

Fig. 3 is an end view,-'with the end of the casing removed. 7

Fig. 4 is a detail end view of the adjusting and locking mechanism.

Fig. 5 is a side view thereof. I

Fig. 6 is a detail view of the adjusting and locking lever.

In the drawings, a denotes the casing within which the mechanism ishoused, this.

casing being provided with a hub b lined with a sleeve 0 in which therotating parts of' the mechanism have their bearings. Mounted withinthis sleeve is a hollow stem 1 having at its inner end a gear 2, andkeyed to its outer end. a worm wheel 3 meshing with a worm 4. Within thestem 1, which may be termed a gear stem, is mounted a stem 5 having atits innerend a T-head 6 worm wheel 7 -meshing with a worm 8. This stem 5may be referred to as the brush stem.

Mounted within the hollow brush stem 5 is an adjusting stem l0'having atits inner end a pinion l1, and its outer end-being squared as at 12 toreceive a ed in the, ends of the T-head are bushings 15, 15 and shafts16, 16. Mounted on the bushings 15, arethe bifurcated arms 20, 20,

their own axes.

wrench. Mountthe shafts 16 are gears 31 meshing with the pinions 27 onthe shafts 26.

From the foregoing description it will be seen that if the worm 4 isdriven from a suitable sourceof power, the worm wheel 3 will cause therotation of the gear stem 1, and through the gear 2 will cause therotapinions 30, 30, the shafts 16, 16, the gears 31, 31, the pinions 27,27 and the It will also be seen that if the worm- 8 is driven from aworm wheel 7 will cause the rotation of the rotate the shafts 16, 16,gears 31, 31, pinions 27, 27, and cause the rotation of the brushes28,28. x

An interchangeable shaft connection 35 is provided for driving eitherone of the worms, 4, 8, but these worms are preferably never drivensimultaneously, and the worm which is not being driven is locked againstmovement by the lever 40 which fits into the recess in the worms and isprovided with a spring dog 41 which will interlock with one of therecessest2'in the plate 43.

It will thus be seen that this machine can be operated in either one oftwo ways: First, the brushes-can be revolved about the axis of themachine and at the same time rotatedon held non-revoluble but rotated ontheir own axes;

mechanism is adapted for operating on round When the brushes tatable,the mechanism is adapted for action on flat, or approximately flat,stock. The stock is fed in through a guide. a: and traverses the hollowadjusting stem 10, moving in the direction of the arrows. Ofcourse thedirection oftravel may be reversed.

The foregoing description is predicated upon one embodiment of theinvention which has been selected for illustration, but I am aware thatthe structure may be modified in various details without departing fromthe spirit of the invention as defined in the appended claims. The termgears is used in the specification and claims to describe a convenientform of drive or driving connection, but I wish it to be understood thatby this term I intend to include any suitable driving connection, suchfor instance as friction devices, etc.

I claim as my invention:

1. In a machine of the character described, a rotatable gear, revolublebrush holders, driving connections between said brushes and said gear,inde pendent means operable one at a time for rotating said gear or forrevolving said brush holders, and an axial passage for stock. v

2. In a machine of the character described, a sleeve having a gear atone end and driving means at its opposite end, a second sleeve .mountedwithin the first, brush holders at one end of said sleeve and drivingmeans at its opposite end, means for driving said brush holders and saidgear independently of one another, driving connections between saidbrushes and said gear, and means for adjusting said brushes toward andaway from one another.

3. In a machine of the character described, a sleeve having a gear atone end and driving means at its opposite end, a second sleeve mountedwithin the first, brush holders at one end of said sleeve and drivingmeans at its opposite end, means for driving said brush holders and saidgear independently of one another, driving connections between saidbrushes and said gear, adjusting the angular position of said brushes.

4. Ina machine of the character described, a casing, a bearing, a pairof hollow stems, one mounted within the other and supported in saidbearing, a gear at the inner end of the outer stem, a T-head at theinner end of the inner stem, shafts mounted in the ends of said T-head,pinions at the outer ends of said shafts meshing with said gear, gearsat the inner ends of said shafts, brush holders mounted at the ends ofsaid T-head,

nections between said at the inner end of outer stem.

and means for shafts carried by said brush holders, pinions on saidshafts meshing with the last mentioned gears, and brushes on said shaftsdriven by said pinions.

5. In a machine of the character described, a casing, a bearing, a pairof hollow stems, one mounted within the other and supported in saidbearing, a gear at the inner end of the outer stem, the inner stem, ofsaid T-head, pinions at the outer ends of said shafts meshing with saidgear, gears at the inner ends of said shafts, brush holders mounted atthe ends of said T-head, shafts carried by said brush holders, pinionson said shafts meshing with the last mentioned gears, brushes on saidshafts driven by said pinions, and means for driving said stems one at atime and for holding the undriven stem. i

6. In a machine of the character described, a casing, a bearing, stemslocated one within another and mounted in said bearing, a gear at theinner end of the outer stem, a T-head at the inner end of theintermediate stem, and a pinion at the inner end of the inner stem,driving means at the outer ends of the outer and intermediate stems,brush holders mounted at the ends of said T-head, means operable by thepinion at the inner end of the inner stem for adjusting said brushholders toward and away from one another, brushes carried by saidholders, and driving conbrushes and the gear 7. In a machine of thecharacter described, a casing, a bearing, a plurality of hollow stemslocated one within another and mounted in said bearing, a gear at theinner end of the outer stem, a T-head at the inner end of theintermediate stem, and a pinion at the inner end of the inner stem,driving means at the outer ends of the outer and intermediate stems,brush holders mounted at the ends of said T-head, means operable by thepinion at the inner end of the inner stemfor adjusting said brushholders toward and away from one another, brushes carried by saidholders, driving connections between said brushes and the gear at theinner end of the outer stem, and means for driving the outer andintermediate stems one at a time and for holding the undriven stem.
